LTC2635HUD-LMO12#PBF

Overview

The LTC2635HUD-LMO12#PBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) featuring an integrated precision reference with a temperature coefficient of 10ppm/°C. It operates from a single 4.5V to 5.5V supply, providing a full-scale output of 4.096V. The device includes rail-to-rail output buffers and is guaranteed monotonic over the automotive temperature range of –40°C to 125°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A power-on reset circuit initializes outputs to high-impedance state.

Feature Summary

Quad 12-bit resolution with maximum integral nonlinearity error of ±2.5 LSB
Integrated 4.096V full-scale reference with 10ppm/°C drift
Power-on reset to high-impedance state for safe startup
Ultralow crosstalk between DACs at 3nV•s

Applications

Automotive systems
Process control and industrial automation
Power supply margining

Procurement Notes

Verify the specific LMO suffix configuration ensures the power-on reset behavior matches system requirements. Confirm the H-grade designation aligns with the necessary 4.5V minimum supply voltage and 4.096V full-scale output specifications for the target application environment.

Selection Notes

Select this component when a quad-channel DAC with high accuracy and automotive reliability is required. The LMO variant is distinct due to its high-impedance power-on reset, which prevents driving loads during initialization. Ensure the supply voltage remains within the 4.5V to 5.5V range to maintain specified performance levels.

Part Context

This part belongs to the LTC2635 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The HUD suffix indicates a 16-pin QFN package with automotive temperature grading. Other variants in the series include different reset behaviors (Z, MI, MX) and full-scale voltages (L-grade 2.5V or H-grade 4.096V).

Replacement Considerations

Direct substitutes within the same family include LTC2635HMI12#PBF or LTC2635HZ12#PBF, provided the power-on reset requirement differs. Verify pin compatibility and electrical parameters before swapping.
